Technician B is correct because regardless of the vehicle's age or emission levels, proper ventilation is necessary to prevent the accumulation of harmful exhaust gases inside the shop. Connecting the shop's ventilation system to the exhaust pipe when the engine is running is a standard safety practice to ensure these gases are safely removed from the work area.
